Towards the Integration of Electricity Sector in EU

2

• Environmental targets, RES exploitation and Integration of an Internal Electricity Market consist the Main and stable policy lines for Europe last decades

• Harmonization of legislation through energy policy “Packages” (Regulations adopted by the European Parliament)

• Specific targets for Emissions, Renewables, Energy conservation and Interconnectors have ben set

• Common market structure (Target Model) to allow for Market coupling – the crucial role of interconnectors

• High degree of harmonization already (Grid Codes, Market rules, common capacity auctions etc.)

• Increased risks due to high RES, market behavior, bulk power transfers etc. Coordinated security procedures/rules/actions should be developed. Several Steps are foreseen towards “coordinated security” Actions in the framework of a Common European Market. Creation of RSCs is the first step.

• The crucial role of TSOs and entso-e; entso-e is the crucial facilitator of the implementations

• Pan-European Legislation on Security and transmission capacities

• Clean Energy Package (CEP) is the next important implementation

RSCs: A Major Step towards Coordinated Security in Europe

6

• Several Steps are foreseen towards “coordinated security” actions in the framework of a Common European Market. Creation of RSCs is the first step.

• What are RSCs?

Regional Security Coordinators or RSCs are entities created and owned by Transmission System Operators (TSOs).

• Their role

The role of an RSC is to assist the TSOs in their task of maintaining the operational security of the electricity system. They perform services for the TSOs, such as providing a regional model of the grid or advanced calculations to tell TSOs which remedial actions are the most cost-efficient, without being constrained to national borders. RSCs issue recommendations to TSOs

• Moreover, according to the SOGL 77(2):

Each TSO must be covered by one RSC, which will be established by EU TSOs (Clean Energy Package)

No more than 6 RSCs in Europe

Evolution of regional coordinated services

7

Timeline refers to entry into

force and implementation of

relevant network codes, all

TSO decisions, and

CEP regulation.

1. European data model delivery (Individual Grid Models from TSOs Common Grid Model) 2. Security Analysis (focus: flows) 3. Regional Capacity Calculation (input for day ahead markets), 4. Short-term Adequacy (short term match generation-load; availability of MW’s; link with balancing) 5. Outage planning coordination(optimized use of assets, incl PST (Phase Shifter Transfo) and HVDC coordination)

Capacity Calculation Regions

8

• Responsible: Transmission System Operator (TSO)

• Participation: Regional Security Coordinator (RSC)

• Methodologies for the calculation of the transfer capacities among different bidding zones (within each country) and regions (Available Transfer Capacity, Flow Based)

• Calculation of total volume of annual and monthly transmission rights

Transfer capacity: The capacity (MW) that can be

commercially exploited by the electricity market

All technical constraints and security criteria are

taken into consideration
